Wireless 101
  • What is Wireless ?

4
Wireless 101
  • There are two main categories of terrestrial
    wireless networks
  • FIXED WIRELESS NETWORKS
  • MOBILE WIRELESS NETWORKS

5
Wireless 101
  • FIXED WIRELESS NETWORKS
  • What is ?
  • IEEE802.11 a/b/g/h/i/n - WLAN (Wireless Local
    Area Networks) a.k.a WiFi
  • 802.11a 54Mbps _at_ 5GHz
  • 802.11b - 11Mbps _at_ 2.4Ghz
  • 802.11g 54Mbps _at_ 2.4Ghz
  • 802.11n 100Mbps _at_ 2.4Ghz
  • The 802.11h standard resolves interference issues

  • 802.11i is the wireless security standard
  • RANGE 25-75ft (802.11a) and 150ft (802.11b/g/n)

6
Wireless 101
  • FIXED WIRELESS NETWORKS
  • What is ?
  • IEEE802.15 - WPAN (Wireless Personal Area
    Networks) a.k.a Bluetooth
  • 802.15 - 720kbs _at_ 2.4GHz
  • 802.15.3 (Ultra Wide Band) 480Mbps _at_ 3.1GHz
    -10.6GHz
  • Used in close proximity to the devices which
    create the PAN
  • RANGE 33ft

7
Wireless 101
  • FIXED WIRELESS NETWORKS
  • What is ?
  • IEEE802.16 WMAN (Wireless Metropolitan Area
    Networks)
  • a.k.a WiMAX (Wireless Microwave Access)
  • 802.16a - 75Mbps _at_ 5.8GHz
  • 802.16c operates in licensed frequency bands
    between 10GHz and 66GHz
  • 802.16e Mobile WiMAX
  • RANGE 30miles

9
Wireless 101
  • MOBILE WIRELESS NETWORKS
  • What is ?
  • TDMA (2G)
  • Time Division Multiple Access
  • Digital Standard
  • Operates at 800MHz, 1,900MHz
  • Data rate of 9.6kbps
  • Can achieve 64k 120kbps data rates

10
Wireless 101
  • MOBILE WIRELESS NETWORKS
  • What is ?
  • GSM/GPRS/EDGE (2G-2.5G)
  • Global System for Mobile Communications
  • General Packet Radio Service
  • Enhanced Data Rates for Global Evolution
  • Digital Standard
  • Operates at 900MHz, 1,800MHz, 1,900MHz
  • Data rate of 9.6kbps to 14kbps for GSM
  • Data rate of 115kbps to 171kbps (max) for GPRS
  • Date rate of 384kbps to 550kbps (max) for EDGE

11
Wireless 101
  • MOBILE WIRELESS NETWORKS
  • What is ?
  • CDMA One/ CDMA2000 (2-3G)
  • Code Division Multiple Access
  • Code Division Multiple Access 2000
  • Digital Standard
  • Operates at 800MHz,900MHz,1,700MHz,1,800MHz,1,900M
    Hz
  • Data rate of 64kbps for CDMA
  • Data rate of 144kbps to 307kbps for CDMA2000

12
Wireless 101
  • MOBILE WIRELESS NETWORKS
  • What is ?
  • WCDMA / UMTS (3G)
  • Wideband Code Division Multiple Access
  • Universal Mobile Telecommunications System
  • Digital Standard
  • Operates at 800MHz,900MHz,1,700MHz,1,800MHz,1,900M
    Hz
  • Data rate of 2Mbps for WCDMA/UMTS

Wireless 101
  • WHATS HOT ?
  • FIXED WIRELESS NETWORKS
  • WiFi (Internet Hotspots)
  • WiMAX
  • Ultra Wideband
  • MOBILE WIRELESS NETWORKS
  • GPRS (Blackberry)
  • EDGE
  • CDMA

15
Wireless 101
  • APPLICATIONS
  • FIXED WIRELESS NETWORKS
  • Enterprise / Branch office connectivity
  • Internet Hot Spots (Hotels, Airports etc)
  • CCTV surveillance / security
  • Sensor monitoring and information transfer
  • Command and Control of Security Forces /
    Military
  • Disaster Recovery (Hurricanes etc)

16
Wireless 101
  • APPLICATIONS
  • MOBILE WIRELESS NETWORKS
  • Text Messaging
  • Voice
  • E-mail

17
Wireless 101
  • IMPLEMENTATION ISSUES
  • FIXED WIRELESS NETWORKS
  • SECURITY
  • BUILDING CONSTRUCTION

18
Wireless 101
  • IMPLEMENTATION ISSUES
  • MOBILE WIRELESS NETWORKS
  • DATA TRANSMISSION SPEED vs APPLICATIONS

19
Wireless 101
  • FUTURE OF THE TECHNOLOGY
  • FIXED WIRELESS NETWORKS
  • Mesh Networks
  • VoIP
  • Multimedia Convergence (voice, video and data)
  • WiMAX networks will be used to compliment the 3G
    networks (which may be hampered by insufficient
    spectrum allocation and cause an effect on data
    speeds)

20
Wireless 101
  • FUTURE OF THE TECHNOLOGY
  • MOBILE WIRELESS NETWORKS
  • WCDMA/UMTS
  • Mobile e-commerce (a.k.a m-commerce)
  • For 3G networks buildout expected difficult since
    smaller cells (as small as 75m)required to
    support 2Mbps data rates
  • In short buildout expected to be slow and less
    effective than anticipated by proponents

21
Wireless 101
  • FUTURE OF THE TECHNOLOGY
  • Next Stop
  • 4G !!
  • (SPECTRUM ALLOCATION IN 2007 -
  • expected data rates up to 20Mbps )
